GLASS TRANSFER MECHANISM Oiiginal Filed Nov. 29, 1927 5 Sheds-Sheet 3 Patented Sept. 19, 1933 1 UNITED STATES PATENT OFFICE GLASS TRANSFER MECHANISM Ira H. Freese, Clarksburg, W. Va., assignor to Hazel-Atlas Glass 00., Wheeling, W. Va., a corporation of West Virginia .10 Claims. (01. 19s-2s) The invention relates generally to mechanism {for transferring glassware from a forming machine to a conveyer, such as a continuously moving conveyer of a fire-finisher. The numerous novel features of this invention will appear from the detailed description, and will be defined by the appended claims.

This application is a division of my application, Serial No. 236,524, filed November 29, 1927; and the subject-matter of this divisional application relates particularly to means for depositing ware on a continuously moving conveyer, and the combination of associated elements.

Referring 'to the drawings: 7 Figure 1 is an end elevational view of the conveyer mechanism shown in combination with a mechanism for transferring the ware from a forming machine to a position over the conveyer.

Referring particularly to Figure 1, numeral 113 indicates the mold of any desired forming machine in which the glass articles to be transferred are formed. Numeral 114 refers generally to an endless conveyer, which is continuously moving, and which carries the desired number of cups 115. Numeral 116 refers generally to a transfer mechanism provided with gripper units 117, by 'which the tumblers or other glass articles are removed from the molds of the forming machine and transferred to a position directly over the path of the cups on the conveyer. It will be understood, of course, that any desired transfer mechanism may be employed, and the particular transfer mechanism shown in Figure 1 is neither described nor claimed herein, as it is the subject matter of a separate application, Ser. No. 448,073, filed April 28, 1930, which application is a division of application SenNo. 236,524, filed November 29, 1927.

The present invention relates to a guiding and delivery mechanism, referred to generally by numeral 118 on Figure 1, by which the transferred articles are deposited in the cups, which are preferably continuously moving.

Arranged beneath a gripper unit, at its point of delivery, is the guiding and delivery mechanism which momentarily receives the tumbler or other transferred article from the gripper unit, and then releases it and deposits it in one 7 of the cups which carries the article through a fire-finisher. This guiding mechanism is mounted on the main frame of the fire-finisher, and in the following description reference is to be had particularly to Figures 2 to 9.

Numeral-119refers to a plate which is spaced above and attached to the main frame of the fire-finisher by means of brackets 120. Of course the plate is spaced above the mainframe of the fire-finisher to permit the cups topass beneath it, 5 as clearly shownin Figure 3. Two arms 121 rest on this plate 119; the arms being pivotally con-- nected by a pin 122, and are intermittently opened and closed bymechanism to be described hereinafter. Each arm carries a half of a liner 123 which is preferably made of soft metal. When these half-liners are brought together by the closing of the arms, they form a receiver, to receive the article delivered by the take-out mechanism. -Thehalf-1iriers are removable in order that difierentliners may be employed to handle the different ware carried through the machine; and of course, the different liners will be shaped to suit the particular ware they are adapted to handle. In this particular instance I have illustrated round'tapered tumblers as the ware being handled, and consequently the liner is shown as round and tapered. The liners may be removably attached to the arms 121 by any desired means; the preferred means as illustrated 10 herein, consisting of a dovetail 124. The dovetail is preferably tapered to provide a rest for the liner. For a reason to appear hereinafter, the arms 121 are preferably dished at their forward ends, asindicated by numeral 125. I

mounted on a pin 132; the pins being attached 7 to the plate 119 by nuts 133. A: finger 134 is attached to or integral with the lower end of each sleeve 131, and these fingers extend inwardly to a position where they are in the path of the. cups, when the receiver is closed, as clearly indicated in Figures 2, '7 and 8. The cups are preferably provided with a fiange 135 to engage the fingers 134, and will be hereinafter described indetail.

For the purpose of closing the receiver I provide rods 136 which have their forward ends pivotally mounted on pins 137 carried by lugs 138 projecting inwardly from the brackets 120; the pins being preferably provided with oil holes 137'. These rods extend rearwardly and pass through suitable openings 139 provided in lugs 140 projecting from sleeves 131. The rods extend on rearwardly beyond the lugs 140, and mounted on the rods, beyond the lugs, are coil springs 141; the pressure on the springs being regulated by nuts 142 threaded on the rear ends of the rods 136. ,Thus when the levers 130 are swung outwardly to open the receiver, the lugs 140 will compress the springs 141' on the rods 136; the rods turning slightly about the pins 137 as pivots. When the flange 135 of a cup passes beyond the ends of fingers 134, thereby releasing them, the springs 141 will force the lugs forwardly, thereby rotating the sleeves 131 and the levers 130 carried thereby; and by means of the pin and slot 1 connections between the levers 130 and arms 121,

the receiver will be moved to closed position.

A complete cycle of operation of the receiver mechanism will now be described, reference being had to Figures 2, 3, 4 and 5-. Attention is also called particularly to Figures 6, 7, 8 and 9, which illustrate in diagrammatic fashion various steps in the transfer. of an article from the receiver to the cups. In Figures 6 and 7 the first cup has received its tumbler, and moved it free of the receiver, and the receiver has closed to receive the next tumbler; but the tumbler has not yet been fed to the receiver, and the second cup is not yet in alignment with the receiver. In Fig.- ure 8 the first two cups have received their tumblers, a tumbler has been fed to the receiver, the third cup is in alignment with the receiver, and the receiver will be opened by the succeeding cup, which is shown in position engaging the fingers 134. In Figure 9, the receiver has been opened, the third tumbler has been deposited in a cup, and the cup has been moved almost far enough to permit the receiver to close, which will occur when the next succeeding cup passes free of the fingers 134.

The continuous movement of an endless chain brings each cup successively beneath the receiver, and the whole mechanismis so timed that just as each cup is almost in alignment with the receiver, the grippers will be separated to deposit a tumbler or other article in the receiver. At this point the flange 135 of the next succeeding cup has come into engagement with the fingers 134; and the continued movement of the endless car- ,rier will cause these fingers to swing outwardly,

the cup is continuously moving, and while it is exactly in alignment with the receiver. Of

course, the manner in which the receiver is opened is apparent from the previous description of the construction. The outwardmovement of the fingers 134 causes the sleeves 131 to rotate, thereby swinging the levers 130 outwardly.

These levers have pin and slot connections with the arms 121, and consequently the outward movement of the levers 130 will cause the arms 121 to swing open to open the receiver; this swinging movement of the arms being allowed by the arcuate slots 128 in the plate 119.

The receiver has thus been opened and the article has been deposited in one of the cups.

The receiver is maintained open by reason of the continued engagement of the fingers 134 withthe flange 135 of the next succeeding cup; and the continued travel of the endless carrier moves the cups with the article forwardly. Of course, the plate 119 is suitably cut away to permit the articles to pass from the receiver to the cups, and to be moved forwardly away from the receiver.

far enough to be free of the receiver, the receiver is quickly closed. In the rapid operation of this mechanism it is essential that the receiver close Just as the continued movement P of the carrier has moved the cup with the article at the instant the cup and article are clear; and

to expedite the closing of the receiver, I have dished the forward ends of the arms 121, as indicated by numeral 125. The manner of closing the receiver will be understood from the foregoing description of .the operation. As the cup with the article is being carried forward the fingers 134 will ride on the flange of the next succeeding cup, and just as the article passes clear of the open receiver, the next cup will pass clear of the fingers 134; thereby permitting the springs 141 to swing the levers 130 inwardly and forcing the halves of the receiver to closed position. This inward movement of the levers 130 also moves the fingers 134 inward into the path of the next cup, and this next cup comes into engagement with these fingers to force them apart just as the preceding cup is in alignment with the receiver, which has just received another article from the take-out mechanism, and thus the cycle is repeated.

It will be understood, of course, that the in vention is by no means limited to the specific construction and operation of the receiver; but I have found that this device constitutes a highly efiicient and most desirable means for receiving ware from the take-out mechanism and depositits arm, a lever connected with each. arm, an in-;

wardly projecting finger operatively connected with each lever, said fingers being engaged and moved outwardly by the cups.
